From: Rabbi Moshe Sofer
To: Rabbi Gedaliah
A community enacts that whiskey distillers must cease operations well before Shabbos, but a visiting rabbi challenges this based on a lenient reading of Maharam Asch. The Chasam Sofer upholds the enactment, demonstrating that Maharam Asch's leniency applies only bedieved when Shabbos arrives during the final passive stage, not as permission to start distilling late on Erev Shabbos.
